Door hinge mounting device for microwave oven

The present invention relates to a door hinge mounting device for a microwave oven. The door hinge mounting device for the microwave oven according to the present invention is constructed such that when a hinge plate 33 provided in a main body 30 of the microwave oven and a hinge shaft 55 provided in a door 50 of the microwave oven are hingedly connected to each other, a supporting rib 65 supports the hinge plate 33 so that the hinge plate 33 cannot be lowered. Further, the supporting rib 65 integrally formed on a choke cover 60 is constructed such that one end thereof is connected to the choke cover 60 and the other end thereof is formed as a free end. The supporting rib constructed as such has a predetermined elastic force depending on its materials and shapes, and thus, the free end of the supporting rib tends to move toward the hinge shaft 55, i.e. a position where the hinge plate 33 can be supported by the supporting rib. According to the present invention, therefore, the door 50 can be firmly mounted to the main body 30 of the microwave oven without any additional components.
